h&role=expert&id=25
• Key Objectives:
• Given a dying patient, the candidate will formulate an
appropriate palliative care plan that ensures optimal control of
pain and other symptoms, maintenance of human dignity, and
recognize the important role of family and social support.
[Back to Basics– Palliative Care – Dr. Shirley Bush]

decision-maker exists, if the patient is unable to express his
wishes
c) the use of pharmacotherapy (e.g., analgesia) for symptom
control, recognizing appropriate indications, side effects, and
complications

[Back to Basics– Palliative Care – Dr. Shirley Bush]
Initiating Opioids: “Worked example”
• Bernard is a 65 year old retired policeman who was diagnosed
with colon cancer 18 months ago.
• After surgery, his disease initially responded to chemotherapy,
but has now recurred with metastases to the liver and
peritoneum.
• He is experiencing increasing abdominal pain.
• He rates the pain as 6/10.
• He has been taking extra strength acetaminophen (1 to 2
tablets 3 to 4 times a day) with minimal effect.
• Q: Bernard has moderate to severe nociceptive pain:
• What opioid would you choose, and why? What starting dose?
[Back to Basics– Palliative Care – Dr. Shirley Bush]
“Worked example”: Answers
• Bernard is opioid naïve.
• Suggested starting doses:
– Morphine (IR) 5mg po q4hrs straight + 2.5 or 5mg po q1-2hr prn as
‘rescue’ dose/for breakthrough pain
– Hydromorphone (IR) 1mg po q4hrs straight + 0.5 or 1mg po q1-2hr
prn
• For ‘rescue’ dose:
– Generally, it is 10% of total daily dose.
– It should be titrated, so could be anything between 5-20% of total
daily dose if needed.
– If patient needs 3 or more ‘rescue’ doses/24 hours, the regular
opioid dose should be increased (assuming opioid-responsive
pain)
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Commencing Opioids
Common starting dose
Starting dose in frail, weak
patients or patients with
severe COPD
Morphine
5 – 10mg PO q4H straight
2.5 – 5mg PO q4H straight
Hydromorphone
1– 2mg PO q4H straight
0.5 – 1mg PO q4H straight
Oxycodone
2.5 – 5mg PO q4H straight 1 – 2.5mg PO q4H straight
(1) Discuss Opioid fears and misapprehension with patient: ‘Morphine Myths’
(2) Do also prescribe a ‘Rescue ‘ dose of IR (Immediate release) opioid for
‘breakthrough’ or ‘episodic’ pain: 10% of total daily dose
(3) Also see OPIOID EQUIVALENCY tables: on One45
[Back to Basics– Palliative Care – Dr. Shirley Bush]
When Commencing Opioids: Manage Potential
Side Effects
• Discuss potential side effects and strategies with patients
• Constipation: occurs in majority of patients and does not
resolve spontaneously
– Regular laxative e.g. senna, lactulose
• Nausea: in up to 2/3 of patients, but usually subsides within
3-7 days
– Antiemetic e.g. metoclopramide, haloperidol
• Somnolence/ Sedation: usually temporary for a few days
– Advise patient not to drive following opioid initiation, opioid
switch, significant dose increase for at least 5-7 days,
or if uncontrolled pain
• Respiratory depression (RR less than 8/min):
• Extremely low risk if appropriate starting dose and appropriate
titration
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Bernard: “Worked example” continued
• Q: How would you titrate the opioid dose up, if Bernard’s pain
remains poorly controlled?
• Method 1: Increase the dose by 20-30%
• Method 2:
– Add up the # of ‘rescue’ doses used in previous 24 hours
– Add these to the total dose of regularly scheduled doses over
last 24 hour period
– Now divide this total by 6 to get the new 4-hourly dose
• Q: Bernard still has pain despite Morphine 10mg po q4hr plus
4-5 PRN doses of 5mg/day: What morphine dose would you
prescribe now?
• Morphine 15mg po q4hrs straight
• Don’t forget to increase ‘rescue’ dose too
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Bernard: “Worked example” continued
• 2 weeks later, Bernard’s pain is under good control (2/10).
He is now on Morphine (IR) 20mg po q4hrs straight, and
taking only 1 -2 ‘rescue’ doses a day. He finds the q4hr
regimen inconvenient.
• Q: What dose of slow release morphine would you start?
• Slow release Morphine 60mg po q12hrs
• And continue IR Morphine for breakthrough pain
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Bernard: “Worked example” continued
• Bernard’s disease progresses. He is managing at home with his
wife, family, and community team (Family physician and home
care nursing). He now develops vomiting from a bowel
obstruction.
• Q: How will you control his pain now that the oral route is no
longer working?
• Change to subcutaneous route.
• Generally, the po: subcut conversion dose for both Morphine and
Hydromorphone is 2:1
• Morphine SR 60mg po q12hrs = Morphine 120mg po/24 hours
• = Morphine 60mg subcut/24hrs = 10mg subcut q4hr straight
• Add subcut option for breakthrough pain (Morphine 5mg subcut
q1hr prn)

Alice: Opioid Rotation Question
• Alice: 73 y.o. metastatic breast cancer
• Lives with frail husband @home, regular CCAC and GP visits
• PPS (Palliative Performance Scale) 50%
• PPS 50% = mainly sit/lie, requires considerable assistance
• Increased pain++ Right hip
• Morphine dose increased from 60mg subcut/24h to 120mg
subcut/24h within the last 7 days….
– Alice is somnolent
– Her husband says she has been confused
– Mild myoclonus of both legs observed
• You, as her visiting MD, are concerned that she is opioid toxic.
• How would you rotate her to hydromorphone?
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Alice: Opioid Rotation Answer
• For opioid rotation Morphine (M) → Hydromorphone (HM)
• 10mg subcut M = 2mg subcut HM (i.e. 5:1)
– See Guidelines for Opioids: Opioid Equivalency tables on One 45
• So 120mg M subcut/24h = 120/5 = 24mg HM subcut/24h
• BUT: equianalgesic dose of the new opioid should be
reduced by 30-50% because of incomplete cross tolerance
• 30% of 24mg HM subcut/24h = 7.2mg
• Thus, suggested final dose = 24-7= 17mg HM subcut/24h

Prognosis: “Doctor: How long do I have to live?”
• How frequently is the
patient observed to
decline?
The Thinker, Auguste Rodin, 1902
– Every Month: estimated
prognosis of months
– Every Week: estimated
prognosis of weeks
– Every Day: estimated
prognosis of days
– Every Hour: estimated
prognosis of hours
BUT with caveat: in setting of advanced cancer, patient’s condition
can change very quickly (Another disclaimer: life expectancy can be longer)

See Chapter 4 in Pallium Palliative Pocketbook
Goals of Care
• Establish patient’s Goals of Care
• Assess the patient and/or family’s knowledge of the illness
and prognosis
• Assess priorities
– Comfort – Allow a Natural Death
– Life-prolongation
– Special events
• Communication: Is everyone on the same page?
– Role for Family Meeting
• Detailed documentation, including ‘level of care’, code status

The Normal Dying Process - The Last Days
•
•
•
•
•
•
•
Weaker: need assistance with all care
Bed-bound
Reduced oral intake - food/ fluids
Difficulty swallowing oral medications
Drowsy or reduced cognition and difficulty concentrating
More time asleep
Some symptoms may increase e.g. delirium, dyspnea
• “Withdraw” - say their goodbyes
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Signs that Death is Imminent: “days to hours”
• Explain these signs to the family and other caregivers:
• CNS: Refractory delirium (in up to 88% of patients @ EOL),
(N.B. exclude reversible causes e.g. urine retention, opioid toxicity),
Reduced consciousness
• RESP: Rate, pattern
– Altered breathing
• Cheyne-Stokes respiration
• Periods of apnea
• Agonal breathing
– Profuse upper airway secretions – “terminal respiratory
congestion” or “death rattle”
• CVS: Weak and rapid pulse, decreased capillary refill
• SKIN: Cold extremities, mottling of periphery (hands, feet, legs)
• GU/GI: Reduced output
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Terminal Respiratory Congestion: “Death Rattle”
•
•
•
•
Inability to clear secretions from oropharynx and trachea
Relaxation of pharynx
Noisy “rattling” respiration
Patients usually unconscious/ semi-conscious and too weak to
expectorate – likely not distressing to patient
– Explain to and reassure family
• Nursing care
–
–
–
–
Nurse semi-prone
Nurse side to side
Maintain scrupulous oral hygiene
Suction rarely required
• Light oral suctioning may be needed – avoid deep suctioning
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Terminal Respiratory Congestion Management contd.
• Discontinue parenteral fluids
• Anticholinergic drugs may be required….
– Reduce production of pharyngeal secretions
– ? Less effective on chest secretions compared with oral
secretions
– E.g. Glycopyrrolate 0.2 – 0.4 mg subcut. q2-4 hr PRN
– E.g. Hyoscine hydrobromide (Scopolamine™) 0.2 – 0.4 mg
subcut. q2-4 Hr PRN
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Still
Active Management of Symptoms
• Prepare patient and family (Difficulty with prognostication)
• Full nursing cares - for patient comfort and dignity
–
–
–
–
–
–
Eyes: Artificial tears, lacrilube eye ointment
Nose: Reassess nasal prongs, salinex gel
Oral hygiene: Regular mouth care, moisture spray, gels
GI: Suppository PRN
GU: Pads, Foley catheter PRN
Skin: Pressure area care (Including mattress)
• Ongoing review and relief of physical symptoms
–  delirium,  dyspnea @ EOL
• Psychosocial (settle affairs)/ spiritual and/or religious needs
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Preparing for Death
• Communication with family: explanation and support
• Clinical management
– Vitals – discontinue
– Investigations – discontinue
– Life-prolonging treatments
• Evaluate benefit, role in ongoing symptom management
• Stop non-essential medications/ ? Discontinue oxygen
– Comfort treatments – continue/ institute
• Appropriate dosing & schedule
– Parenteral route for medications (subcut. route generally) when
patient no longer able to swallow/ in anticipation of this
• Review role for Medically Assisted Hydration & Nutrition
• Deactivate Implantable Cardioverter Defibrillator (ICD)
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Review Venue of Care
• Knowledge of options available
• ? Hospital vs. Palliative Care unit vs. hospice vs. nursing
home/LTC vs. home
• Single room if possible
• If needed, liaise with Palliative Care Hospital Consult service
– Liaise with Family Physician – As Early as possible
– Community palliative care team (24 hr cover) - RPCT
– Referral to community nursing service (CCAC)
• Supply of drugs with medication orders, hospital bed and
other equipment, ?Foley catheter, ? Dressings, ??Oxygen
• Insert indwelling Subcut. butterfly needle
• Urgent ambulance home/ completed MOHLTC DNR order
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Planning for Crises
• Community: Supply of emergency drugs at home
– E.g. Subcut. opioid, neuroleptic, antiemetic, benzodiazepine,
anticholinergic (EOL)
• Risk of Hemorrhage
• E.g. Carotid hemorrhage in Head and Neck (H&N) cancer
• E.g. Massive GI bleed, massive hemoptysis
– Discuss with family and staff
– Green towels
– Catastrophic order/ Crisis pack
• Midazolam 5- 10mg subcut. (or I.M.), +/- Usual opioid rescue dose
and repeat q5 minutes PRN if needed
– Stay with patient (At home: advise family not to call 911 – DNR
order in place)
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Essential Medications at EOL ……
• Cessation or subcut. conversion of oral medications
– Consider continuous Subcut. infusion
• ? Opioid (e.g. for pain, dyspnea)
• +/- Antipsychotic for delirium
– E.g. Haloperidol, methotrimeprazine (Nozinan™)
• +/- Sedative agent for refractory delirium, refractory dyspnea
at the end of life
– E.g. Midazolam, lorazepam, methotrimeprazine (Nozinan™),
phenobarbital
• +/- Antiemetic
• +/- Anticholinergic for respiratory secretions
– E.g. Glycopyrrolate, hyoscine
• Review parenteral fluids/ oxygen
[Back to Basics– Palliative Care – Dr. Shirley Bush]
Caring for Patients - and Families - at the End of Life
•
•
•
•
•
Address fears and concerns
Reassurance where appropriate
? Hearing and Touch last senses to go
Suggest notifying family/ friends, especially if overseas
Consider allied health support (social work, spiritual care,
psychology) if not already involved
• Ensure family members looking after selves (eating, drinking,
sleep)
• “Keeping vigil”: Give permission for family to leave room and
take breaks, or create a roster for family shifts
• Enquire if any cultural or religious/spiritual needs for end of
life care, and after death
